What the numbers mean
The average bill is not what every household pays. Bills vary within a company's region, depend on whether the home has a water meter, and are reduced for customers who get financial support: around 2.5 million households are expected to receive support in 2026-27, with an average discount of around 40%.
A high bill is not the same as a bad company. Bills reflect how much investment each company is funding and what its region costs to serve. Southern Water charges the most, £759, and South West Water is next at £740; Thames Water's bill is close to the national average at £658 and rises by only £3.
